Nope. Here's the volume in question that started it all
llist volumes output:
MediaId: 4
VolumeName: clients-0004
Slot: 0
PoolId: 5
MediaType: File_clients
FirstWritten: 2006-09-10 11:05:01
LastWritten: 2006-09-10 23:26:29
LabelDate: 2006-09-10 11:05:01
FirstWritten says 11:05, but the volume wasn't Recycled until 11 hours
later, and first written another half hour later (I walked away and forgot
to mount the device...)
